adapted for use in connection with molds employed or used in themanufacture of glassware. One of the objects of the present invention isto provide a device of this character which will venable the operator atpredetermined intervals during the blowing operation to open and close.

the mold sec tions with facility.

A still further important object of the invention is to provide astructure of this character which enables the operator to have free useof his hands for the blowing operation and to control the opening andclosing ofthe mold sections by means of the feet.

A still further important object of the invention will be found toreside in the novel frame supporting structure andthe arrangement of themold and operating levers therefor permitting of the efficient operationof the workman therewith.

The present invention contemplates the provision of a suitableplatformen which the work- ,man may stand and on which there isarrangedin a novel manner the mold especially constructed for the molding ofthin glassware in one piece. On the platform are arranged suitableactuating levers for opening and Vclosing the sectional mold sections ofthe stem mold, vand for opening and closing the blow-heads of the bodymold, said operating levers being arranged on the platform. at aconvenient position with respect tothe operator for elicientworkmanship.

v and embodiment of the invention, the reference numeral 6 generallydesignates the supporting table which includesatop 8 having secured onthe underneath side thereof adjacent the rear and front edgestransversely disposed angle irons I0. f From the underneath side of thethe angle ir served these top 8 and secured to ons I0 are legs I2.Aswill be oblegs I2 are constructed of angle iron 1937, serial No.r133,243

and have secured in spaced relation from the lower ends thereoftransversely extending angle iron supports I6. Upon the supports I6 arearranged the angle iron members I8. As will be observed, these membersproject outwardly from the front portion and have secured transverselythereof to the free end a cross member of angle iron construction 22. Atthe intersections of the legs and the members I8 there is furthersecured another angle iron cross member 26 forming a support for themold platform 28. Upon this mold platform therey is secured a moldsupport and mold structure of the type fully disclosed and described inmy pending application. Briefly, this includes as illustrated a pair ofspaced pedestals 30 and 32 which are secured to the platform 28 and risetherefrom on the upper end of which by means of bolts 34 there issecured a plate 36 which has a central opening therein. A shell 38 ofcylindrical shape rises around concentrically of the opening in theplate in which there is rotatably mounted the body mold. Above the shell38 the rotatably mounted body mold 31 has on opposite diametricallydisposed sides pivotally mounted thereto the sections 48 and 42 formingthe head. As clearly illustrated the sections are provided withlaterally extending arms 46 for a purpose to be more fully hereinafterdescribed.

'Ihe stem mold-is formed of semi-cylindrical half-sections 48 and 49each section having an apertured ear 50 respectively turning on a commonpivot 52 which is secured to the support 28.y

Extending transversely of the member I8 and secured thereto is a rod 68having secured cenutrally thereon spaced collars 64 and 66. Thesecollars as clearly illustrated are secured in position on the rod `bymeans of the set screws 66 and have arranged in the upper portionthereof transversely extending slots in which there are securedupstanding leaf spring members 68 which are secured within the slots bymeans of the screw bolts T0. The members 68 are provided in their upperfree ends with spaced eyes I2 separated by means of a longitudinallyextending slot 14. The spring members 64 and 66 are connected to `thelugs 54 and 56 of the sectional stem mold sections by means of the links14. As will be observed the links are downturned at one end and arereceived in the apertures in the lugs and at the other end are providedwith eyes which are received in the slot 14 and secured therein by meansof a bolt extending through the eyes I2 and the eyes in the links. Tothe rod 60 adjacent one end thereof there is secured another collar bymeans of a set screw 82 and having in the slotted end thereof ahorizontally extending spring leaf member of similar construction 84. Itwill be observed that this spring member 84 extends horizontally andforwardly and has pivotally mounted at the free end thereof the free endof an operating rod 86. 'I'his rod extends upwardly through an aperturein the table and isprovided on its upper end thereof with a head 88. Thesectional mold sections are normally maintained in their open positionby means of the spring 90 which has one end secured to an extendedportion of one of the levers 14 and the other endto the reartransversely extending angleriron member |6. It will thus be seen, thatin the open position of the mold sectons the operating lever or rod 86is in its upwardly extendedv position the bowl section being adapted tobe closed upon a depressing ofthe head 88. llt is to be noted furtherthat the leaf springs 64, 66 and 84 permit of an abrupt and positiveclosing of the bowl sections and a snap action opening of the same uponthe release of foot pressure from the operating head 88.

It will be observed that the head sections 40 and 42 are normallymaintained in their` closed position by their respective weights. Thehead sections are adapted to be opened and permitted to close bymeansvof gravity throughthe operating mechanism which includes asemi-circular shaped cross head 96 having secured thereto by means ofscrew bolts depending pins 98 which pins are adapted to engage thelaterally extending arms 46 of the head sections. Adjacent the free endsof thecross member 96 there are secured upwardly extending arms and |02.These arms extend upwardly throughA apertures in the platform or top 8and on the arm |02 there is secured a head |04. Between the head |04 andthe top of the table 8 there is provided a spring |06 encircling the arm|02 normally maintaining the member 96 in an uppermost position andholding thepins 98 out of engagement with the arms 46 of the headsections permitting the head sections to assume their normally closedposition by means of gravity. Upon a depressing of the head |04 the pins98 contact the arms 46 opening the head sections. In thecentral portionof the front end of the table 8 there is provided an inwardlydirectedV-shaped slot ||0. This slot as will be observed', is. directly abovethe U-shaped cross head member and permits of access from the front endand top of the table to the head of the mold.

In operation, the head sections are normally maintained in their closedpostion by gravity, the operator standing on top of the table 8 closingthe sections of the'sectional stem mold by depressing the head 88. Theoperator after obtaining a suliicient quantity of molten glass'on thefree end of his blow pipe inserts the same through the mold head intothe mold and after completing the molding operation raises one foot fromthe head 88 effecting an Vautomatic opening of the mold sections formingthe stem of the ware, and upon a depressing of the head |04 by the otherfoot opens the mold head permitting, of the completed blown ware toberemoved from the mold. rIt will be observed, that the workman oroperators hands are entirely free for the blowing operation, the controlof the mold during the molding operation being effected by the feet ofthe operator.
